XP 100 in 458 win mag?

I was wondering how a 458 win mag would fit. I don't know if the round could be turned in to fit or not.

Okay, just for giggles, I went and grabbed a couple things out of the gun room: a loaded round of .458 Winchester Magnum ammo and my XP-100, chambered in .221 Fireball.

As you can see, it's longer than the action opening, but it funnelled in there pretty easily. With the bullet's ogive resting up against the itty-bitty chamber opening and the rest of the overlength in the locking lug area, there's maybe 1/4" of space left over. So it should work pretty smoothly, although getting the empties to fall out would likely require tipping it to the right and shaking it a little.

Personally, were it me, I'd go for it if the price was right. I've got a bunch of moulds for .458" bullets and would plan on light loads. Down in Trapdoor Springfield .45-70 territory. I agree that the shorter length versions of the case would be the way to go for any sort of efficiency/performance and it might prove to have disappointing accuracy as-is: still, it'd be fun to play with and find out for sure.
 
A gun shop in NH had a XP 100 converted to 416 Taylor.
As far as 458 goes,I might buy it but let someone else test fire it.
 
I have a Ruger #1 African in 458 Winchester Mag, it is a very heavy rifle and still the round gets my undivided attention when one is touched off. I cannot concieve of what that little Remington must feel like.
 
I once read about one in "American Handgunner", something like thirty years ago. The first time the guy shot it, he was prone on his stomach. The scope came back and smacked him in the face, leaving a cut over his eye. From then on, he learned to shoot it in the recumbent position. He shot an iron ram with it. He got a hit and the ram spun out of sight. When it was examined, it had been hit in one leg, which broke off from the base side and bent at a right angle away from the body, in the direction of the flight path of the bullet.
 
You may have a .458 American designed by Frank C. Barnes in mid 1962. It was a .458 shortened from 2.5" to 2". It was designed to shoot bullets in the 300-400 grain weight. It is more related to the 45-70 than the .458. It is sometimes called the .458x2". If this is the case then a full sized .458 should not chamber.

I think JD Jones chambered some XP-100s for the .458x2" in the 70's or 80's.

I have a Savage Striker in 308 and an SSK Industries T/C in 375 JDJ and they are a handful but fun to shoot. I handgun hunt with these and they are very accurate.
 
For anyone who comes across this thread

OK, so it's a year ago and no-one has bumped this thread. Guess I'll chime in.

Helloooooooo, (hearing echo)

For those who care?,
Check this out www.americanhandgunner.com/1979/HJF79.pdf

Back in the mid 70s a man by the name of John Towle, T-N-T Arms was not only experimenting, but actually built a .458 XP with dual grips.

His comments as I recall was "just to see if it could be done". The gun was not for sale due to obvious reasons. Read the story.

I actually had communicated with him via snail-mail back then and had a quote for a .358 at approx $750.00. In 70s dollars that was a alot.

Anyway, I hesitated for about four months before I decide to go for it and when I tried to contact him again, he was no-where to be found. I don't know if the Feds shut him down or what, but he just seem to dissappear.

Would love to find one of those .358s today.

Just my two cents worth...........
 
follow-up

BTW, just to clarify, T-N-T also built .358 XPs as well and the recoil was described as "managable".

The .458, (full size), from a prone position, and dual gripped, rose perpendicular to the firing line when fired...., hence.... "not for sale"

Anyone ever heard of John Towle from T-N-T? He also was big into building custom comp PPC guns....
 
What if you put a silencer on it? Recoil and noise would go down but it would still be one hell of a powerful handgun...
 
I wasn't familiar with the XP 100 so at first I assumed it was supposed to read XD. So I was picturing someone trying to shoot a 458 out of a little Springfield XD.....
 
NWGS, thanks for that blast from the past. John Towle crafted some fine firearms, and those big single shots were a hoot to shoot.

Should anyone be inspired to build their own, leave off the forward grip. They are not legal without ATF license at this time.
 
Back when I was shooting handgun metallic silhouette in the 1970s, the biggest XP I ever saw was a .458 American (2" belted case.) The owner did not actually shoot it, he just showed it off and used his (downloaded) .308.
 
.458 Win Mag pistol?

Get ATRS to make you a gill brake. It's what Rick has for his 18.5lbs .50BMG, tames the recoil.

I'd buy that thing ON THE SPOT.
 
A gunsmith in NE Ohio built an XP in 585 Nyati. Pretty crazy. He was into big guns, had an A-Square in 500 A-Square on the wall for sale.

I have one of the last Remington XPRs in .35 Remington that came into California. The magazine holds 4 .35 Rems which feed very well. I shoot 180 grain Speers with Reloader 7 out of it's 14" barrel at a chronographed 2200 fps +-. The Burris 2-7 Handgun scope hangs on with 3 rings. It shoots 2" 100 yard groups from a rest-all day. The recoil isn't bad as the rig weighs 4.5 pounds. When I loaded up some 220 bullets at 1900 fps it started getting pretty rough to shoot off a bench. I thinks some physics are involved here.
 
JD Jones and Lee Jurras come to mind. Those guys were all over exotic single shot hand cannons in the early 80's. Gun Digest used to run some pretty amusing articles about those pistols and the wildcat rounds developed for them.
 
I have an inherited T/C Contender pistol in .45-70 Gov't. I shot this thing 1 time to see what it was, and that was enough for me. Maybe if I could attach a stock or something, but that was one tough cookie, and I know a 458WIN is huge compared to this.

Heck, My Winchester model 71 in 348 kicks really hard and its a rifle! 458 in a pistol? I'd rather watch then shoot on that one.
 
I like my XP in 7mm BR as it is about perfect.

The plan book that I built my 50 BMG from had a pistol version in it. All I can say from owning and shooting the rifle version is "no thanks" on the pistol version.

A really good muzzle brake would make this shootable. All the gas coming out would make the brake work, knocking recoil down considerably.
Gary Reeder would be the guy to talk to, since he's Mr. One shot handgun hunting.
 
My XP in 7mm BR is nice to shoot, (although it is going up for sale as I no longer have a place to shoot it)

I can't imagine firing some of the previously mentioned cartridges, let alone the noise and recoil.....
